GOLDQUEST COMMENCES ESIA FOR ROMERO PROJECT AND ENGAGES ADELAIDE CAPITAL FOR INVESTOR RELATIONS

Goldquest Mining Corp. has formally commenced the environmental and social impact assessment (ESIA) for its 100-per-cent-owned Romero gold-copper project in the Dominican Republic.

In July, 2025, Goldquest conducted seven community meetings across the project area and related surrounding communities close to Romero, with approximately 400 local residents participating. These sessions provided a transparent and inclusive forum to share project information, listen to community concerns and gather early input to inform the assessment process.

The ESIA work plan has been developed in alignment with the terms of reference (ToR) issued by the Ministry of Environment and Natural Resources (MIMARENA) of the Dominican Republic. To support future access to international financing and uphold best practices, the ESIA is also being designed to meet internationally recognized standards, including the IFC Performance Standards, the Equator Principles and guidelines from the International Council on Mining and Metals (ICMM).

This robust approach contributes to the advancement of several United Nations Sustainable Development Goals (SDGs), including SDG 6 (Clean Water and Sanitation), SDG 8 (Decent Work and Economic Growth), SDG 12 (Responsible Consumption and Production), SDG 13 (Climate Action) and SDG 15 (Life on Land).

"The launch of the ESIA marks a fundamental milestone for Romero," said Luis Santana, chief executive officer of Goldquest. "By aligning with both national and international frameworks, and by engaging meaningfully with our local communities from the outset, we are laying the groundwork for a transparent and sustainable development path."
